' Application tiled September ing Devices, of which the following is a full,

,had to the accompanying drawings,

clear, and exactdescription, reference being which form a part of this specification.

My invention relates to electric heating devices as stoves, toasters, etc.

The object of my invention is to provide an electric heating device, and more especially an electric toaster,vwhich will be of simplilied construction enabling decreased manufacturing costs and which at the same time will be of increased efficiency in operation.

More particularly, by virtue of my invention, l provide greatly simplied means for supporting andfsupplying current to the resistance elements within the body of the toaster.

Having now indicated in a general way the nature and purpose of my invention, l will proceed to a detailed description thereof with reference to the accompanying drawings, in which l have illustrated the invention as ,embodied in an electric toaster, and in which- Fig. 1 is a plan view of an electric toaster embodyingv my invention'with the top plate removed.

Fig. 2 is a front elevation of the toaster, partly broken away.

Fig. 3 is a cross-sectional view.

The body a of the toaster is provided with a perforated top plate b and a perforated bottom plate 0. The body is supported on legs d positioned beneath the lcorners and secured tothe body by means of bolts e which pass through the bottom and top plates and serve to secure them to the body.

Within the body and at opposite sides thereof are secured a pair of supports f, f of insulating materials, secured to the body by means of bolts g `which also pass through handles h and se* cure them to the body.

-Opposite faces of the supports are channelled horizontally, as at t', for the reception of the sidesof a tray j inserted into the body through an aperture k in the front and the supports bemg Town, PENNSYLVANIA, ASSIGNOR, nu MILLER, or ELIZABETHTOWN, PENN- mnc'rmc HEATING DEVICE'.

adapted for the support of the article to be toasted, as a piece of bread.

Bus bars m having holes in the edges are secured to the top and bottom of the suplports f, f', and coiled resistance wires n, hav-l Ing their ends hooked for engagement in the holes in the edges of the bus bars, extend between the bus bars. The supports are provided With protectingvianges t, above and below, against which the bus bars bear and which serve to insulate them from the body and to align them, as shown in Figure 1.

Contacts o, o insulated from the body are carried thereby and are connected by wires p to bolts g and r respectively. f The bolt g extends vertically through the support f into contact with one of the bus bars on the top of support f and secures it thereto, while the bolt r serves to secure one of the bus bars to the under side of support f. The bus bars and resistance wires 'are so connected that the current entering at (say) contact o will pass through bolt g intoV the first bus bar on the topof support f, across the first resistance wire to the irst bus bar on top `of support f', through this bus bar to the second resistance wire and back and forth until it reaches the last bus bar on top of support f from which it will pass through a bolt s, through support 7" and contacts with a bus bar on the under side of' support f. rlhe current then passes back and forth through the resistance wires connecting the bus bars on the under side of supports f and f until it finally passes out through wire p and contact o llt will now be obvious that in accordancey with my invention a toaster is provided the top, bottom, body andlegs of which are secured together by means of four bolts eX- tending through the body at its corners, while the resistance elements are connected by means of bus bars supported on a pair of unitary supports which serve also to support the tray adapted to carry the article to be toasted, and the securing means for which serve to secure the handles to the tray.

lt will be noted that the current is transmitted from the upper resistance elements to the lower by means of securing bolts for opposite bus bars, without the necessity for excess wiring.

llt will be understood that although l have described my invehtio particularly in oom neetion with an electric toaster, 1 do not limit myself to such an embodiment as it is obvious that the invention is equally applicable tO any other form of electric heatlng device as a stove, heater, etc.

aving now fully described my invention what I claim and desire to protect by Letters Patent is:

1. An electric heating device comprising, in combination, a body, oppositely disposed supports secured within the body, bus' bars secured to the top and bottom of said supports, resistance elements extending between said supports in contact with said bus bars on the top and bottom of said supports respectively, and means serving to secure a bus bar on the top and bottom of one of said supports and adapted to transmit current through said support from one of said last mentioned bus bars to the other.

2. An electric heating device comprising, in combination, a body, oppositely disposed supports secured within the body, bus bars secured to the top and bottom of said sup-1 ports, resistance elements tally between the supports andl aii'ording connection between the bus bars on the top and bottom of the su ports respectively, and means extending t rough the supports extending horizonadapted to transmit current from the top to the bottom of the supports.

3." An electric heating device comprising, in combination, a

body, oppositely disposed Y attento supports secured within the body, opposing faces of said supports being ohannelled horizontally, bu's bars tom of said Supports, resistance elements extending between the supports in contact with the bus bars on the top and bottom of the supports respectively, and a tray the sides of which are adapted for insertion into the channels in said supports lwhereby said tray will be supported within the body.

4. An e ectric heating device comprising, in combination, a body, top YJand bottom plates,'legs, and means extending vertically through the interior of saidbody and engaging said top and bottom1 plates and legs whereby said topand bottom plates and legs are secured to said body.

5. An electric heatin in combination,` a bo y, top and bottom plates, legs, means extending within said body and engaging said top and bottom plates and legs whereby said top and bottom plates and legs are secured to said body, a support adapted to be secured within the body, a handle adapted to be secured outside of the body, and means engaging said handle and extending into said bodyand enga ing saidsupport adapted to secure said handle and support to said body. v

In testimony hereunto set my device comprising,

of which invention, I have hand, at Elizabethtown,

on this-31st day of August, 1921.
